Bonjour tout le monde 
Alors voila j'ai un shield GPRS seeed studio (v2) de ce type : http://www.evola.fr/product_info.php/shield-gprs-p-479
aucun soucis pour l'envoi de SMS, mais ca se complique pour l"envoi de données sur un serveur.
j'ai installé le programme donné en exemple ici : https://docs.google.com/file/d/0B6Qn4nam5VvfNGNlYTYyNjYtZjg3ZS00ZWVhLWI2MWItMzBiMjRiOTk4ZmFm/edit
en prenant soin de le modifier en version arduino 1.0 (les bytes, write etc ...) comme ceci :
//Remember when using GPRS Shield with Seeeduino Stalker v2.0
//please dismount the OK_READ Jumper (i.e. open it).
//This will disconnect the Battery Charger IC's OK pin from
//the microcontrollers Digital Pin 7 and hence allow unhindered
//communication with GPRS Shield using NewSoftSerial Library.
//Replace the following items in the code:
//1. Replace the Access Point Name "TATA.DOCOMO.INTERNET"
//and the DNS server name "10.6.6.6" in the AT+CGDCONT and AT+CSTT
//commands with those of your own service provider.
//
//2. Replace the Pachube API Key with your personal ones assigned
//to your account at pachube.com
//
//3. You may choose a different name for the the data stream.
//I have choosen "TMP102". If you use a different name, you will have
//to replace this string with the new name.
//
#include <SoftwareSerial.h>
#include "tmp102.h"
//Please fetch tmp102.h and tmp102.cpp from "Stlker logger AM06 Serial.zip"
//available from Seeeduino Stalker v2.0's Wiki Page
#include <Wire.h>
float convertedtemp; // We then need to multiply our two bytes by a scaling factor, mentioned in the datasheet.
int tmp102_val; // an int is capable of storing two bytes, this is where we "chuck" the two bytes together.

le prog semble fonctionner mais je vois rien sur mon compte sur cosm.com
quelqu'un aurait il déjà utilisé ce système ?
merci
